IMPROVEMENT IN CUT-OEE Eon RELAYS AND OTHER ELECTRO- MAENETIc INSTRU-MENTS.

The Schedule referred to in these Letters 4Patent and making; pau-t ofthe lame.

'To all whom it may con-cern Be it known that I, FREDERIC M. PERRY, ofBarton, in the coul'itywof Orleans and State of Vermont, have invented anew 'and improved Ont-Out for ElectrojMagnetic Instruments; and I dohereby decla-rc that the following is a full, clear, and exactdescription thereof, which will enable others skilled in. the art tomake and use the same, reference being had to the accompanying drawingformingr part of thisspccification. l f This invention relates-toiinprovents in cut-oi' apparatus for electro-magnetic instruments, andconsists in a platinnl'n point` mounted-on a lever, pivoted adjnstablyto the brass plate of the relay or machine,

by means of a` yoke and set-screw, so arranged that the lever may beattached `and the point may bc adjusted relatively to the armaturewithout taking the Y machine ont of circuit. y

Figure l represents a section ofmy vimproved :apparatus, and a pai-tietelevation of an electro-magnet, the latter being in dotted vlines -andFigure 2 is a perspective view of my improved apparatus.

Similar let-ters of reference indicate corresponding part-s.

A represents the brass plateof therelay or machine, to which the leverisA attached; Y

B is the lever; O is the platinum point, attached to the said lever; and

D is the armature of the machine, workng. in conjunction with thisplatinum point.

'Ihis lever B is vpivotcd to -thc clamp? E, and connected to the brassplate A by the clamp E and the clamping-screw F,so that it may bereadily attached to any machine in usc, without taking it outlet'circuit- Y The leve-r is raised on-its pivot, askshn'wnlin dot-ted linesat G, to break the circuit, andV v.tnrned down, as represented bytheblack lines in fig.,2, to close it.

When the lever is down, it rcstsfon the brass bars Hof the relay,between which thc larmature of' the magnet vibrates.

A as a temporary substitute for the said bars H, in the absence of them.The lever B is provided with athuinb-bt, K, to

be nsed for working it.

Having thus described my invention,- 'g I claim as new and desire tosecure by Letters l3at- The combination of the level' B, platinum pointC,

' clamp E, and clamping-screw F, when arranged for application to theplate A and to the armature D, all substantially as specified. FREDERICM. PERRY.
